Flexible fast-convolution processing for cellular radio evolution

no code implementations5 Feb 2022 Juha Yli-Kaakinen, Toni Levanen, Arto Palin, Markku Renfors, Mikko Valkama

Orthogonal frequency-division multiplexing (OFDM) has been selected as a baseline waveform for long-term evolution (LTE) and fifth-generation new radio (5G NR).

Phase Noise Resilient Three-Level Continuous-Phase Modulation for DFT-Spread OFDM

no code implementations12 Oct 2021 Markku Renfors, Ismael Peruga Nasarre, Toni Levanen, Mikko Valkama, Kari Pajukoski

A novel OFDM-based waveform with low peak-to-average power ratio (PAPR) and high robustness against phase noise (PN) is presented.

Joint Positioning and Tracking via NR Sidelink in 5G-Empowered Industrial IoT: Releasing the Potential of V2X Technology

no code implementations15 Jan 2021 Yi Lu, Mike Koivisto, Jukka Talvitie, Elizaveta Rastorgueva-Foi, Toni Levanen, Elena Simona Lohan, Mikko Valkama

The fifth generation (5G) mobile networks with enhanced connectivity and positioning capabilities play an increasingly important role in the development of automated vehicle-to-everything (V2X) and other advanced industrial Internet of Things (IoT) systems.

Frequency-Domain Signal Processing for Spectrally-Enhanced CP-OFDM Waveforms in 5G New Radio

no code implementations3 Aug 2020 Juha Yli-Kaakinen, AlaaEddin Loulou, Toni Levanen, Kari Pajukoski, Arto Palin, Markku Renfors, Mikko Valkama

These schemes are based on dynamically adjusting the overlap periods and extrapolating the CP samples, which make it possible to align the FC blocks with each OFDM symbol, even in case of variable CP lengths.

Mobile Communications Beyond 52.6 GHz: Waveforms, Numerology, and Phase Noise Challenge

no code implementations19 Dec 2019 Toni Levanen, Oskari Tervo, Kari Pajukoski, Markku Renfors, Mikko Valkama

In this article, the first considerations for the 5G New Radio (NR) physical layer evolution to support beyond 52. 6GHz communications are provided.
